The first time the story appeared in print with the title The Little Engine that Could was in 1920 in a set of books entitled My Book House that was sold in the U.S. via door-to-door salespersons.[2] The My Book House version began “Once there was a Train-of-Cars; she was flying across the country with a load of Christmas toys for the children who lived on the other side of the mountain.”[2] The story was labeled “As told by Olive Beaupré Miller”; the first edition gave credit to Bragg, but subsequent editions did not as Miller subsequently concluded that “the story belonged to the realm of folk literature.”[2]
